I’d like to see, at all airports, signs that clearly label the individual gates. Perhaps the most practical way to do this is to have markings on the ground (similar to taxi lines).
The markings would direct you to the gates after you vacate the runway; somewhere along the taxiway. And as you approach the gate area, there should also be markings that specify which aircraft(s) can park at each respective gate.
Obviously the goal is to create a more realistic and immersive experience. I realize that this may have been brought up and discussed before, but I thought it might be worth mentioning again.
